[timestamp] Error Failed to write data to the file [Filepath\file.vbk].

Cause

Cyclic Redundancy Check is an algorithm allowing Veeam Backup & Replication to check backup consistency. The error indicates that the backup chain did not pass this check, and the target files got corrupted. This can also indicate problems on the physical storage where the backups are stored.

Solution

In the Veeam console, open the Backups section and locate the problem backup job. Right-click the job name and select "Delete from disk." After that is done, restart the job.
